Greetings,
from a spectrum of 25Mhz (GSM-900) i would like to sample as
many 200khz bands as possible. Since the data rate of the usb
bus is only 8Mhz, i cannot sample all of this 25mhz wide band.
Still 8Mhz would be enough to transfer 40 distinct 200khz wide
bands, which are spread over the 25Mhz band. As far as i understand,
i would have to use 1 daughterboard, 1 ADC and 40 DDCs for this
to work. Is it possible to build an FPGA image that does that?
If not, is it possible on the USRP2?
Thanks for helping
Sascha
